摘要:
The invention relates to a method and a device for controlling a vehicle that comprises an engine (11) arranged to drive at least one pair of half shafts (12) and to drive at least one pump (15). The pump is arranged to supply a hydraulic system (14) comprising at least a first hydraulic component (4, 5) with hydraulic oil. According to the method, the power consumed by the hydraulic system is determined. In addition, the determined consumed power is compared with a reference value, and if the detected consumed power exceeds the reference value, the maximum available power for the hydraulic system is limited. The power limitation is carried out by the maximum available movement of at least a first flow-regulating valve (16, 17, 22) in the hydraulic system being limited.
摘要:
The invention relates to a system for moving an implement of a vehicle from a first position to a predetermined, second position. The system comprises at least one hydraulically controlled means of moving the implement, an operating valve (20) for regulating the supply of hydraulic oil to the hydraulically controlled means, and a control member (11) hydraulically connected to the operating valve (20) for regulating the operating valve, the control member being designed for operation by the driver of the vehicle. The system further comprises means (22) for reducing the pressure in a pilot line (21) to the operating valve (20), and a control unit (15) connected to the pressure-reducing means (22) in order to control the pressure of the hydraulic oil that is delivered to the operating valve in the pilot line.
